CONT'IROL FOR SYNCEBONIZED GUNS.

Application filed March 9, 1922. Serial No. 542,430.

To all whom it may concern:

Be it known that we, HERBERT O. RUssELL and CHARLES LEIGH PAULUS, citizens of the United States, residing at Detroit and Day- 5 ton, in the counties of Wayne and Montgomery and States of Michigan and Ohio, have invented certain new, and useful Imrovements in Controls forSynchronized runs, of which the following is a specification.

This invention relates to a control mechanism for synchronized gear of machine guns, the object in view being to provide simple\means for the purpose of starting 16 and stopping the fire of a machine gun when operated by a gun control or synchronized gear. The mechanism is especially adapted for a synchronizing gear or un control in which the impulse is transmitted from the 20 mechanism to the machine gun by a wire cable within a casing; .The starting and stopping of the firing o eration of the machine gun is accomplis ed by shortening and lengthening the efiective length of. the

casing is shortened, enough clearance is allowed both ends of the cable so that the trigger of the machine gun will not be operated.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement herein fiilly described, illustrated and'claimed.

In the accompanying drawings Figure 1 is a broken plan new of the mechanism. 7 y j Figure 2 is a diametric section through thesame with parts in'elevation.

Figure 3 is an end view of the same.

40' Referring to the drawings, 1 designates a cylindrical housing in which is arranged a sliding sleeve 2 actuated by a spring 3 within the housing 1. Within the sleeve 2 is a rotatable. sleeve 4,,the rotation of which is produced by means of a Bowden wire control cable running to the-control handle or lever (not shown) operated b the gun- -...ner. Thecable 5, enters the' ousing 1 through a tubular extension or guide 5' 'which isdisposed tangentially with relation to' the center of the housing as shown in casing relatively to the cable. In case the.

said sleeve from rotating, inasmuc union nuts 8 and 9 on both ends of the Figure 3, the Bowden wire control cable being wrapped around the-inner end of the rotatable sleeve 4 which is formed. with a.

A pin orstud 11 in one end of the rotating sleeve 4 works in a cam slot 12 and thus imparts to the sleeve 2 a sliding movement outwardly, thereby lengthening the overall length of the casing 6. One end of the spring 3 is fastened to the rotating sleeve and the other end to the sliding sleeve; consequently when the rotating sleeve is turned, torsion is put u on the spring 3 suflicient to rotate the rotatmg sleeve 4 back into lace and thus shorten the over-all length 6 the casing when the pull upon the Bowden wire control cable is released. A pointed screw 11' limits the inward and outward movement of the sliding sleeve and also revents as the mechanism are identical, the mechanism may be turned end for'end if desired.

Having thus described our invention, we claim;

1. A. control for synchronized guns embodying a tubular casing, an im ulse cable therein, and means for varying t e eflt'ective le'hgthof. said casing relative to said im- 'pulsej cable, said means comprising a slidable sleeve fastened to one end of the casing,

a housing for said sleeve, and means in said housing operable to move said sleeve in the direction of length of the casing.

2. A control for synchronized guns embodying a tubular casing, an impulse cable therein," and means for varying the effective len h of said casing relative to said im ulse cab c, said means comprisinga slidable s eeve fastenedto'one end of the casing, a bone" for said sleeve, a rotatable sleeve in sai housing cooperating with said slidable sleeve to shift the latter in the direction of length justing the primary effective length of the of the casing, and means for rotating said casing relative to said impulse cable. rotatable sleeve.
